Seawater Temperature from Salinity and Density

Compute in-situ temperature, given salinity, density, and pressure.

Usage

swTSrho(
  salinity,
  density,
  pressure = NULL,
  eos = getOption("oceEOS", default = "gsw")
)

Arguments

salinity: in-situ salinity (PSU)
density: in-situ density or sigma value (kg/m\(^3\))
pressure: in-situ pressure (dbar)
eos: equation of state to be used, either "unesco" or "gsw" (ignored at present).

Value

In-situ temperature in \(^\circ\)C on the ITS-90 scale.

Details

Finds the temperature that yields the given density, with the given salinity and pressure. The method is a bisection search with temperature tolerance 0.001 \(^\circ\)C.
